摘　　要：现有的用来评价具有多个独立子系统的复杂系统相对有效性的YMK DEA模型假设不存在规模收益,且不能评价系统的纯技术有效性.在假设存在规模收益的条件下,建立了评价系统纯技术有效性的C2GS2 ISS模型,将效率分解为纯技术效率和规模效率,从而可以找到系统行为低效的根本原因.最后用该模型对我国制造业发展进行了评价.The existing DEA model used to evaluate the relative efficiency of system with independent subsystems assumes that there exists no returns to scale, and one can't obtain pure technique efficiency by using this model. In this paper, C^2GS^2-ISS model that allows decision-making units to exhibit variable returns to scale is introduced. This model can be used to evaluate the pure technique efficiency of decision-making units. Efficiency of every decision-making unit is divided into pure technique efficiency and scale efficiency, so the real reason of inefficiency is obtained. In the end, the model is applied to evaluate the manufacturing industry's development all over the country.
